Definitions

  • the invention relates to a mobile device for activating an electrical component, especially a switch, which is arranged inside a housing, with a recess provided on the housing, at least one elastic key element accessible from the outside, which is accommodated in the recess, and the key element has a contact means, wherein the contact means is pointing toward the interior of the housing, in order to activate the electrical component, and a carrier which holds the key element on the housing.
  • a housing for an electronic key which has electrical and electronic parts inside the housing.
  • the housing is designed with a through opening, which can be covered by an electrical key pad with a key, the key being provided with an extension by which a switch inside the housing can be activated.
  • the key pad is fastened to a carrier for mounting on the housing.
  • the carrier here serves as a fastening means for the key pad.
  • the problem of the invention is to create a device of the aforesaid kind, whose assembly expense can be reduced.
  • the special benefit of this invention is that the assembly of the key element on the carrier no longer has to be done manually by a worker, since the two parts form a common assembly unit that can be fastened onto the housing in simple fashion.
  • the number of parts of the mobile device can be reduced, while the carrier ensures a reliable fastening of the key element on the housing.
  • the key element on the other hand, is made to be elastic in its material properties, so as to absorb a pressing force acting from the outside, while at the same time the contact means is elastically deformed accordingly and this brings about an activation of the electrical and/or electronic component.
  • the assembly unit can be fastened to the housing in positive or non-positive fashion.
  • the carrier and the key element form a 2-piece injected molded part.
  • the carrier prefferably has at least one detent element, which also extends though a hole in the recess of the housing, and there is a clip connection between the detent element and housing.
  • the detent element can be elastically deformable, so that when mounting the assembly unit on the housing the detent element is elastically deformed from its position of rest and abuts directly against the housing in the installed state of the assembly unit, with the detent element engaging behind a wall of the housing. This brings about a reliable fastening thanks to this described clip connection of the assembly unit on the housing.
  • the detent element is advantageously fashioned as a hook at its end region, which ensures a reliable purchase of the assembly unit on the housing.
  • the key element can be fashioned as a key pad with a plurality of keys, each key having a contact means that is located inside an opening of the recess of the housing and extending in the direction of the electrical component.
  • each contact means can be associated with its own electrical component.
  • the keys preferably form a common structural part, which forms the key pad.
  • the housing is configured in the region of the recess with the opening so that when the key element is activated, the contact means can move reliably inside the opening in the direction of the electrical component, so that the activating of the electrical component can be triggered.
  • the housing can have a top and a bottom part, the assembly unit being fastened to the top part.
  • the top and the bottom part can be joined together in positive and/or non-positive manner.
  • Inside the housing there is an inner space that is closed off by the top and bottom parts.
  • the electrical component can be provided on a board, for example.
  • the board can be provided with yet other, not more specifically described electrical and/or electronic components.
  • the key element is elastically configured so that after a corresponding activation of the electrical component by the contact means the key element is elastically deformed back to its original position if no further force is exerted on the key element from the outside.
  • the individual keys of the key pad can be separated from each other by corresponding haptic means.
  • These haptic means can be configured as a rib, for example, or as a groovelike depression between the respective keys.
  • the housing can have means of sealing off the interior of the housing in the region of the recess. It is conceivable that the means will extend as a projection in the direction of the key element and penetrate into the key element by its free end. Thus, a reliable sealing can be obtained between the housing and the assembly unit, especially the key element.
  • the means can be configured pointlike and encircles the opening for the contact means and the hole for the detent element. When the assembly unit is mounted on the housing, the key element will be deformed in the region of the pointlike means, while at the same time the pointlike means will protrude into the key element.
  • the clip connection between the detent element and the housing ensures that the key element is held reliably and with a defined force on the pointlike means.
  • the pointlike sealing means thanks to its extending around the opening and the hole in the housing produces a reliable sealing off of the inner space of the housing.
  • the contact means is arranged inside the opening of the housing such that a free space exists between the contact means and the housing, so that the contact element is oriented in the region of the opening at a distance from the housing. If a corresponding pressing force is exerted on the key element, the key element with its contact means will move inside the opening in the direction of the electrical component. It is advantageous in this case for the free space between the contact means and the housing to get smaller during a corresponding activation of the electrical component. Thus, the free space offers the contact means sufficient freedom of movement. It is likewise conceivable that, when the electrical component is activated, the contact means comes to rest against the housing and therefore no more free space exists when a key element is activated. In both cases described, the free space that exists when the key element is not activated provides the user with a good haptic behavior of the key element.
  • the carrier can consist of a first material and the key element of a second material, while the first material has a first plastic and the second material a second plastic, wherein the first plastic has a greater mechanical resistance than the second plastic.
  • the second material can be a silicone, a thermoplastic polymer, especially a material made of TPE or, for example, TPU.
  • the key element has a protective lacquer on its exterior.
  • This protective lacquer can provide protection against the weather, scratches, etc.
  • the detent element moves along the sliding surface and is elastically deformed.
  • the detent element can likewise be designed with corresponding sliding surfaces that slide along the sliding surfaces of the hole in the housing.
  • the device is an ID transmitter for a keyless activation of a lock of a motor vehicle.
  • FIG. 1 a three-dimensional side view of a mobile device, where a key element, designed as a key pad, is inserted inside a housing,
  • FIG. 2 a first sectional view along the key element of FIG. 1 ,
  • FIG. 3 a three-dimensional side view of the key element, which forms with a carrier a common assembly unit,
  • FIG. 4 a view of part of the housing of FIG. 1 and FIG. 3 ,
  • FIG. 5 a second sectional view along the key element of FIG. 1 .
  • a mobile device being an ID transmitter for a keyless activation of a locking device of a motor vehicle.
  • the mobile device has a housing 10 , which comprises a top part 11 and a bottom part 12 .
  • Inside the housing 10 there is arranged an electrical and/or electronic component, which can be activated by a key element 31 , inserted in the housing 10 .
  • the elastic key element 31 in the present sample embodiment is designed as a key pad with three keys 31 . 1 , 31 . 2 , 31 . 3 .
  • the key element 31 in the present sample embodiment is inserted in a recess 13 of the housing 10 , shown in FIG. 2 and FIG. 3 .
  • Each key 31 . 1 , 31 . 2 , 31 . 3 of the key element 31 has a contact means 32 .
  • the contact means 32 has the form of a plunger 32 .
  • the plunger 32 is formed of the same material on the key element 31 .
  • the contact means 32 serves to operate and activate the component 50 , which is fastened to a board 51 inside the housing 10 , see FIG. 4 and FIG. 5 .
  • the contact means 32 is oriented toward the inside of the housing 10 , and when the key element 31 is not activated the contact means 31 is at a distance from the component 50 .
  • the key element 31 especially a key 31 . 1 , 31 . 2 , 31 . 3
  • the contact means 32 makes contact with the component 50 .
  • a signal can be triggered to lock and/or unlock a locking device of a motor vehicle. It is likewise conceivable that the activating of the component 50 will trigger an opening of the trunk or other actions on the motor vehicle.
  • the mobile device is in data communication with the motor vehicle in this case, especially with a control unit arranged inside the motor vehicle.
  • various signals are relayed to the motor vehicle, for example, by sending and/or receiving units that are arranged both on the mobile device and on the motor vehicle.
  • a carrier 35 is provided, which reliably holds the key element 31 on the housing 50 .
  • the carrier 35 forms with the key element 31 a common assembly unit 30 , which is made clear in FIG. 3 .
  • the carrier 35 in this case is made of different material than the key element 31 .
  • the carrier 35 consists of a first material and the key element 31 of a second material.
  • the first material has a first plastic and the second material a second plastic, with the first plastic having a greater mechanical resistance than the second plastic. This means that the key element 31 is more easily elastically deformable than the carrier 35 , which provides for a reliable fastening of the assembly unit 30 in the recess 13 on the top part 11 of the housing 10 .
  • the second material is a silicone. It is also conceivable to have the second material be a thermoplastic polymer that is used for the key element 31 .
  • the carrier 35 is designed with detent elements 36 , each of which extends through a hole 15 in the recess 13 of the housing 10 .
  • the hooklike detent element 36 engages behind the top part 11 and lies directly against the wall of the top part 11 , so that a clip connection is formed between the detent element 36 and the housing 10 .
  • each key 31 . 1 , 31 . 2 , 31 . 3 is coordinated with a contact means 32 , an opening 14 and two holes 15 , with one detent element 36 reaching through each hole 15 .
  • the top part 11 of the housing 10 on which the assembly unit 30 , especially the carrier 35 with the key element 31 is installed, is shown in FIG. 4 .
  • the top part 11 has three openings 14 , one for each contact means 32 of the key element 31 .
  • the six holes 15 are provided one for each detent element 36 .
  • the assembly unit 30 with the carrier 35 and the key element 31 is a 2-component injection molded part, which is set as the assembly unit 30 into the top part 11 , with the carrier 35 introduced into the recess 13 .
  • each detent element 36 slides on a slanted sliding surface 15 . 1 of the hole 15 , whereupon the detent element 36 moves along the sliding surface 15 . 1 and is elastically deformed.
  • the free end of the detent element 36 exits from the opening 15 , whereupon the detent element 36 is elastically deformed back and takes up the position shown in FIG. 2 .
  • the housing 10 has means 16 of sealing off the interior of the housing 10 in the region of the recess 13 .
  • the means 16 extends as a projection in the direction of the key element 31 and its free end penetrates into the key element 31 . In this region, the material of the key element 31 is compressed. Thus, a reliable sealing of the inner space of the housing 10 can occur.
  • the pointlike means 16 having the shape of a collar, encircles the holes 15 as well as the openings 14 .
  • the contact means 32 of each key 31 . 1 , 31 . 2 , 31 . 3 is arranged inside the opening 14 of the housing 10 so that a free space 1 exists between the contact means 32 and the top part 11 , so that the contact means 32 when the key element 31 is not activated is oriented in the opening 14 at a distance from the top part 11 .
  • the key element 31 is designed with a protective lacquer on its surface, which protects the key element 31 from environmental factors such as moisture or scratching, etc. Furthermore, the material of the key element 31 is designed such that, after activating the key element 31 , the key element 31 is elastically deformed back to its original position, so that the contact means 32 is again at a distance from the respective component 50 .
  • the component 50 is a switch. As shown in FIG. 5 , three switches 50 are provided for the three contact means 32 belonging to each key 31 . 1 , 31 . 2 , 31 . 3 .
  • the individual keys 31 . 1 , 31 . 2 , 31 . 3 are separated from each other by a projecting rib 33 .
  • This rib 33 serves to reinforce the key pad. Thanks to this reinforcement, the individual keys 31 . 1 , 31 . 2 , 31 . 3 can be clearly distinguished when initiating their switching movement.
  • the provided rib 33 at the same time has the function of a touch ridge that can be haptically sensed by the user.
  • the space lying beneath the board 51 in FIGS. 2 and 6 can be used, for example, to accommodate other electrical and/or electronic components or the battery itself.
  • a reliable holding of the assembly unit 30 on the top part 11 is improved in that a depression 17 is provided between every two openings 14 (see FIGS. 4 and 5 ), and a projection 34 formed on each key element 31 is accommodated in the depression 17 .
  • the projection 34 in this case is adapted to the shape of the depressions 17 and is held in the depression 17 in positive and/or non-positive fashion.
